Is there a KiCad symbol and footprint for the SMF30A?
Yes. The symbol is Diode:SMF30A and the footprint Diode_SMD:D_SMF, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMF30A?
SOD-123FL, with 2 pins. Its footprint is drawn on this page.
Where is the SMF30A datasheet?
MDD publishes it: the Datasheet link on this page opens it.
Where can I order the SMF30A?
JLCPCB lists it as part C364281, with 118,375 in stock; the sellers' links on this page open their listings.
What can replace the SMF30A?
Parts like it in the library: the SMF30A by hongjiacheng, the SMF30A by 晶导微电子, the SMF30A by TWGMC and the SMF30A by GOODWORK. Check their datasheets: a part that fits the footprint may still differ in its ratings.
